Two Math teachers are having a conversation as they go to lunch. Pointing across the street, Mr. Smith says, “ That’s one of my sons sitting over there in the park “

Mrs. Jones asks Mr. Smith how many children he has.

“ My son has as many sisters as he has brothers. Each of his sisters has twice as many brothers as she has sisters. “

How many sons and daughters does Mr. Smith have?

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
